[Zope] dtml-let

[Charlie Reiman]

dtml-let introduces a new scope. Don't use it. Instead consider one of two
options

1) Use dtml-set. You'll have to download and install the product, but it can
do this sort of thing.

2) Use python. I'd probably do it this way unless your table is very tall.
The python would query the underlying data, munge it and compute totals, and
present the easily rendered list of dicts or list of brains to the final
dtml. You'd also be set to switch to ZPT before Chris hits you with a stick.
